PROBLEM TO BE SOLVED: To improve productivity without spoiling such an advantage of a precipitation polymerizing method that the particle size of a polymer to be obtained can be adjusted to be in the range of 1-10 μm and in a narrow particle size distribution, and removal of an additive by cleaning etc., after producing the polymer is not required. ! SOLUTION: A copolymer of a 3-chloro-2-hydroxypropyl methacrylate and a polymerizable monomer including a methacryloyl group or an acrylyl group is provided. A method for producing a copolymer of a 3-chloro-2-hydroxypropyl methacrylate and a polymerizable monomer including a methacryloyl group or an acrylyl group is also provided which comprises polymerizing the 3-chloro-2-hydroxypropyl methacrylate and the polymerizable monomer including a methacryloyl group or an acrylyl group in a solvent in which the 3-chloro-2-hydroxypropyl methacrylate and the polymerizable monomer including a methacryloyl group or an acrylyl group are dissolved, but the polymer thereof |
